Title: Video recorder with improved recording of the audio signal
Inventor: KLUTH HANS-JUERGEN ING GRAD
IPC: H04N5/93
Filed: 1981-06-05
Abstract: In a video recorder with helical-track recording and switching between two heads, the audio signal is also recorded on the helical tracks in the form of a frequency-modulated carrier. The interference (12) in the audio reproduction, intrinsically occurring due to the head change, is reduced by the fact that the amplitude of the recorded audio carrier (Figure 2c) is in each case increased approximately by the factor (2) by a gating pulse (16) during the head change. <IMAGE>

Title: Process for the preparation of i-alkenes
Inventor: MUELLER HANS JOACHIM DR
IPC: B01J27/06
Filed: 1981-09-19
Abstract: n-Alkenes can be converted catalytically to i-alkenes if a mixture which contains at least one n-alkene and hydrogen is brought into contact at a temperature of 400 to 600 DEG C and for a residence time of 0.2 to 20 seconds with an Al2O3 or SiO2 catalyst which is specially activated and doped with halogen compounds of elements of the third to fifth main group and second to eighth subgroup of the Periodic Table and/or hydrohalic acids. The special activation consists in calcining an aluminium hydroxide or aluminium oxide hydrate or a silica gel having a content of volatile ammonium salts before doping with expulsion of these volatile ammonium salts to give Al2O3 or SiO2. The catalyst is used for the conversion of the n-alkenes in an agitated catalyst bed. The catalyst can be subjected to separate regeneration by continuous or batchwise discharge of an aliquot part and fed back into the agitated catalyst bed again after regeneration.

Title: Capacitor arrangement having a device for monitoring and disconnecting an electrical capacitor
Inventor: HUBER ROBERT
IPC: H01G4/38
Filed: 1981-09-25
Abstract: A capacitor arrangement having a device for monitoring and disconnecting an electrical capacitor, especially a heavy-current capacitor, which is arranged in a gasproof housing inside which there is an overpressure resulting from excessive heating of the capacitor, from which the operation of an electrical switch, which is connected in the supply circuit of the capacitor, is derived. The switch is controlled by a pressure sensor which senses the pressure inside the housing and triggers when the maximum permissible overpressure is reached. In addition, self-monitoring of the disconnection protection and monitoring of the capacitor housing for leakage points that occur can take place by means of the pressure sensor or a second pressure sensor. To this end, a small minimum overpressure is set for the inside of the capacitor housing, so that the switch is also triggered as soon as the internal pressure falls below the minimum overpressure.

Patent DE-3144327-A1 (DE)
Title: Coin-sorting and -counting machine
Inventor: JAHN ARTHUR
IPC: G07D9/00
Filed: 1981-11-07
Abstract: The invention relates to a coin-sorting and -counting machine which is usually arranged in a manually transportable housing. It is concerned essentially with the design of the driving disc which, in known versions, can lead to faults especially in the transfer from the driving disc on to the run-off strip. Thus, for example, an unsuitable dimensioning can cause the reception of two coins in one recess or, this being in respect of the increasing proportion of large coins, the overriding sorting out of the latter, with the result that the machine is stopped prematurely when the large-coin box is full. The object of the invention is, therefore, to design the sorting mechanism, especially the driving disc, so that the coins run off at an equal spacing in a greatly differing coin-size sequence. The solution for achieving this object envisages the arrangement of two radially directed recesses of different size which are respectively one behind the other and are arranged on the periphery of the driving disc, the larger recesses being so dimensioned that they can in each case simultaneously intercept the largest coins, but not two smaller coins from the coin assortment. The depth dimension of the recesses is less than the thickness of the thinnest coin, so that the coins project reliably above the driving disc (4) and, if the rolling capacity is insufficient, are made to roll by the run-off strip. <IMAGE>
Patent DE-3150851-A1 (DE)
Title: Coded solid-state access device
Inventor: MOORHOUSE JOHN HURLEY
IPC: E05B49/00
Filed: 1981-12-22
Abstract: A coded key-operated solid-state access system for controlled access to a large number of electronic circuits through the use of appropriately coded keys comprises a test and detection system which is put into operation by inserting one of the coded keys into the key guide. After insertion, the key subsequently couples a multiplicity of switches which enable a timer to energise for a first time interval of the key insertion a circuit which normally unlocks the locked tumblers, and which switches enable an optical coupling circuit, after rotation by the key and in accordance with the possibility of the key code, to read the codes of the tumbler. The optical coupling circuit is matched and connected to a comparator which operates to couple the code read from the tumbler to a correspondingly coded circuit. If the code does not match a corresponding circuit, the first time interval of the timer is lengthened, and the circuit which has unlocked the tumblers is deenergised, as a result of which it locks in the tumblers and the key. If the code matches a circuit, the time measuring circuit is reset for a different time interval so that the tumblers can return to their original position for the withdrawal of the key. Access to the corresponding circuit is obtained after coupling.
